In her science project Martina is observing how fast kitchen condiments can be dissolved in water. She put 8.5 ounces of water into each of 5 containers. Complete that equation that models the total amount of water,w, Martina used

The equation that models the total amount of water, w, Martina used can be represented as:

w = 8.5 * 5

This equation represents multiplying the amount of water in each container (8.5 ounces) by the number of containers (5) to obtain the total amount of water used.
